When God makes a promise to you, and you recognize God's promise, and you acknowledge God's promise, and you commit to wait on God's promise to come to pass, refuse to allow circumstances and people to force you into actions of doubt. Gen. 16:2-3, was one of those times. Abraham's circumstances, and his wife encouraged him to act without God's direction by having a son by Hagar, instead according to God's promise. We still have tension between the Arab's and the Jew's because Abraham did not wait on God.
Be patient and wait on God to fulfill His promises to you just as He promised.
